6 FAQs about [Principle of boost capacitor energy storage circuit]

Why is a capacitor important?

Capacitors are essential elements in electrical and electronic circuits, crucial for energy storage and management. When a voltage is applied across a capacitor, it accumulates electrical energy in the electric field formed between its plates.

What is the recommended voltage range for a boost capacitor?

If the full 12V to 36V voltage range is required, the boost capacitor value must be reduced to 2.7nF (Figure6-2). The recommended configuration for the 20V to 36V range is to place the capacitor is placed between VDDand VBOOSTas shown in Figure6-3. V DD Input C T Gnd V BOOST Gate Sense- Sense+ TTL Input +12V to +20V MIC5021

Why do I need a boost converter?

As the output voltage of one cell supercap is not higher than 2.7 V, a boost converter is needed to step up the output voltage to power the GSM/GPRS module or MCU. The GSM/GPRS module voltage is normally higher than 3.6 V. The low input voltage boost converter can fully utilize the energy of the supercap and extend the backup power time.

What is a capacitor & how does it work?

A capacitor is a device designed to store electrical energy. The process of charging a capacitor entails transferring electric charges from one plate to another. The work done during this charging process is stored as electrical potential energy within the capacitor.

What is a low input voltage boost converter?

The GSM/GPRS module voltage is normally higher than 3.6 V. The low input voltage boost converter can fully utilize the energy of the supercap and extend the backup power time. The TPS61022 provides a power-supply solution for portable equipment and IoT devices powered by various batteries and super capacitors.

What is the process of charging a capacitor?

The process of charging a capacitor entails transferring electric charges from one plate to another. The work done during this charging process is stored as electrical potential energy within the capacitor. This energy is provided by the battery, utilizing its stored chemical energy, and can be recovered by discharging the capacitors.
